fix(rectification): persist the collect stem on the same assistant turn

The live question slot disappeared on refresh because it was never written to assistant_message. Attach the current collect_spoken prompt to that turn before finalize so chat history keeps it.

+## BUG-487 | 口述采集题干在动作图标下方，刷新后聊天历史丢失
+
+- 状态：resolved
+- 首次发现：2026-09-02
+- 最近更新：2026-09-02
+- 影响面：POST `/api/rectification/agent` opening/evidence、`finalize_agentic_rectification_turn`、重生成、`.rectification-question-slot__prompt`
+- 用户现象：开场助手气泡只打招呼，采集题干出现在点赞/复制/重生成图标下面的问题槽。刷新页面后气泡里没有那句题干，因为它从未写入 `assistant_message`。
+- 触发条件：新 Case `action=opening` 且 `current_question.kind=collect_spoken`；或同一采集题仍有效时刷新/重进会话。
+- 根因：BUG-471 / BUG-485 把口述题干真源放在 GET `current_question.prompt` 的直播槽。槽位不是 turn 历史。`shouldPersistFocusPromptTurn` 在已有非空正文时禁止第二条助手消息，所以刷新只能看到打招呼。
+- 修复：`composeCollectSpokenAssistantText` 按题干字符串精确身份接到同一条正文末尾。opening/evidence 在 `finalizeTurn` 之前 idle-persist 当前题、用 `answer.delta replace` 替换直播正文，并把组合文本写入 `p_assistant_message`。重生成同样回贴当前 `collect_spoken` 题干。前端仅在最新助手正文尚未带上该精确题干时才渲染采集槽；选择卡仍走问题槽。不 bump Skill 10.0.14，不放宽确认门，不用正文字符串判断「有没有问过」。
+- 验证：`rectification-collect-prompt`；`rectification-spoken-collect` 锁槽位兜底与 `composeCollectSpokenAssistantText`；`rectification-v9-agent` 锁 finalize 前写入组合正文；`rectification-v9-regenerate` 锁重生成回贴；`agent-voice-copy-contract` 锁服务器接题干并写入聊天历史。
+- 防复发：口述采集题干必须出现在同一条已完成助手消息里，刷新后仍在 `turns[].text`。不得只靠问题槽直播。不得再追加第二条 opening 题干消息。不得用 `includes` / 正则扫描正文决定是否已提问。
+- 相关记录：BUG-449、BUG-461、BUG-469、BUG-471、BUG-485
+- 复发自：BUG-485（槽位可见但不是聊天历史）
